PROHANDS Gripmaster Hand Exerciser, Finger Exerciser (Hand Grip Strengthener), Spring-Loaded, Finger-Piston System, Isolate & Exercise Each Finger

I have a few of these, in different tensions, and they are great.Primarily, I got the light and the medium to improve my finger strength for playing piano, but my partner recently had an injury that required exercising her tendons to rehabilitate her hand, I also invested in the XX light and X light. Though too easy for anyone with "normal" strength in their hands, they prove to be challenging enough to rebuild strength for those who need to start at a lower resistance.The design is elegant, as each finger can be exercised individually as the springs are independent of each other, or you can just squeeze them all for a full hand workout. I found this particularly useful for strengthening my pinkie for playing guitar...as we use all the other fingers more frequently in our daily lives, our pinkies tend to not have much "grip".They sit comfortably in the hand, thanks to the contoured foam, and can be used in either hand by simply turning them around.One observation would be that they are not cheap, so you may be better finding one in a shop and working out your starting point before investing in the next one up from Amazon.If you need to develop finger strength and grip, or need a little booster to your rehab following an injury, these gizmos are a perfect choice.

It's a nice product as it helps you exercise individually your fingers.I must confess that I thought this light tension version to be lighter. I am a woman with a small hand and I find it difficult to use it properly with my left hand (I'm right-handed).

The media could not be loaded. If you’re reading this review there is a strong chance you’ve come looking for some Kind of insight and guidance on what tension / strength to buy. I know I trawled many reviews on Amazon, many YouTube videos and other pages.What I realise is every person is different and expectation and needs differ to.What I bought : Blue / light tension / 5 pounds pressurePurpose : to help increase / improve grip strength for Bouldering / Rock ClimbingAbout me : so I’m a 41 year old man, 6ft 14 stone with average fitness and what I would say is average strength in my hands. I’ve been bouldering for 6 weeks and ride a bike daily to and from work. So up to recently, have been doing nothing particularly centred around my hand or grip strength - unless you consider the grip used on my bikes handle bars. I use a computer all day and console game regularly.When making the decision I was stuck between the choice of blue light tension and red medium tension. After much research I opted for blue on the basis that whilst it might be easier for me, repetition was going to be the key and I could work my way up - this was preferential to going in too heavy and struggling to compress the grip master, straining my hands to early on and becoming frustrated.I was glad I opted for the blue - it’s relatively easy to compress all the way in a single press, but does require some effort on continuous reps. When used in repetition you can feel the resistance and feel your hands building up, I’ve only used it for a short time but can tell that it will have benefits for climbing and building up grip strength - especially when using finger tips to grip. The individual finger grips are good also highlighting the difference in strength between them and being able to work them individually.Being a desk worker I have it at my desk and pick up during the day, it’s a fun distraction / desk toy also.Side note - if you are interested in building pure strength i.e prefer lower reps & heavier weights, you might be a little disappointed in the resistance on this model and might benefit from the the next model up - a weight lifting colleague found it disappointing. But as a starting point for high reps and for someone who doesn’t do weightlifting this was good for me!

I am a software developer and I bought for when I have a spare few seconds while at my desk; also I play guitar so I wanted to increase the strength of my index finger so I could barr the whole 6 strings. My other goal was to be able to do pullups just with hooking my fingers around the bar. The last goal was to increase the strength and control of my pinkies.I can say assuredly that this thing works. I didn't even take it seriously, and in the first week was just messing about to see if I could press one of them down with my pinky (although I used all 4 fingers, but mainly looked at how my pinky was holding up). Within minutes of putting the thing down, suddenly picking light objects seemed easier. Next go at it minuts later seemed easier. A week later, my pinky was so much stronger, so I could just about use the black version.Btw, my technique is simply holding down for 10-20 second periods.If you're interested in finger strengths, increasing your pinch grip and do other sorts of strength training on your fingers, this will do the job nicely. Truly unique and fantastic product 5+

These are great. I've used different types of hand exercisers before, but these are a really great way to do it. To be able to exercise individual fingers and assess where the strengths and weaknesses are is really great. It's built really well, doesn't seem like it would break down very easily. Really cannot complain about it at all. All I would say is that this is almost certainly too easy for an average grown man. I bought the next one up, and that was too easy too. If you're thinking about getting one, start with the one above this and then step down if you need to if you're an adult.

Nothing wrong with the item, but read the item description carefully when ordering.I admit this is my fault, but I ordered this thinking it was the 9lb black version, as that was what was clearly shown in the photograph. I didn't notice that the item description was for the 3lb yellow version and was therefore very disappointed when it arrived. £11 and one week's rehabilitation wasted. Don't make the same mistake I did.
